MYOFIBRILLAR DISRUPTION & MUSCLE PROTEIN SYNTHESIS

本研究探讨了肌原纤维 中断和肌肉蛋白合成率（MPS）后， 同心（Con）或偏心（Ecc）阻力的孤立回合 六名接受力量训练的男性。 MPS是根据 使用引发的， 评估期中点的恒定输注技术 运动后约24小时。 我们的结论是， 抗阻运动阶段对骨骼肌的破坏性最大， 训练减弱了这种效应， 在训练的无活动5天后，中断基本上得到修复。 科目

This study examined the relationship between myofibrillar disruption and muscle protein synthetic rate (MPS) following an isolated bout of concentric (Con) or eccentric (Ecc) resistance exercise in six strength-trained males. MPS was calculated from the enrichment of L-[1,2-13C2]leucine in biopsies using the primed, constant infusion technique with the midpoint of the assessment period being approximately 24 h post-exercise. We conclude that the Ecc phase of resistance exercise is most disruptive to skeletal muscle, that training attenuates this effect, and that exercise-induced fibre disruption is essentially repaired after 5 d of inactivity in trained subjects.
